NORM.DIST DAX Function (Statistical)
Returns the normal distribution for the specified mean and standard deviation.
Syntax
Parameter | Attributes | Description |
---|---|---|
X |
The value for which you want the distribution. |
|
Mean |
The arithmetic mean of the distribution. |
|
Standard_dev |
The standard deviation of the distribution. |
|
Cumulative |
A logical value that determines the form of the function. If cumulative is TRUE, NORM.DIST returns the cumulative distribution function; if FALSE, it returns the probability mass function. |
Return values
The normal distribution for the specified mean and standard deviation.
Examples
-- NORM.DIST returns the normal distribution for the -- specified mean and standard deviation -- -- NORM.DIST ( Value, Mean, StandardDev, Cumulative ) -- -- NORM.S.DIST returns the standard normal distribution -- (has a mean of zero and a standar deviation of one) -- -- https://en.wikipedia.org/wiki/Normal_distribution DEFINE TABLE SampleData = { 2, 4, 4, 4, 5, 5, 7, 9 } VAR Mean = AVERAGE ( SampleData[Value] ) VAR StandardDev = STDEV.S ( SampleData[Value] ) VAR Vals = GENERATESERIES ( 0.0, 10, 0.5 ) VAR CumulativeTrue = TRUE -- Cumulative distribution function VAR CumulativeFalse = FALSE -- Probability density function EVALUATE ADDCOLUMNS ( Vals, "Normal Distr.", -- Probability density function FORMAT ( NORM.DIST ( [Value], Mean, StandardDev, CumulativeFalse ), "#,0.00000" ), "Normal Distr.
